## GPU Texture Caching
The GPU has 2 Kbyte Texture Cache<br/>
The Texture Cache is (maybe) also used for CLUT data - or is there a separate
CLUT Cache - or is the CLUT uncached - but that'd be trash?<br/>
There is also a CLUT cache that is preserved between GPU drawing commands. The CLUT cache is invalidated when different CLUT index values are used or when GP0(01h) is issued. It is unknown if the CLUT cache overlaps or is shared with the Texture Cache.
If polygons with texture are displayed, the GPU needs to read these from the
frame buffer. This slows down the drawing process, and as a result the number
